Who was studied 19,445 Finnish ancestry cases, 270,460 Finnish ancestry controls, 19,445 British ancestry cases, 270,460 British ancestry controls, 12,024 Chinese ancestry cases, 67,845 Chinese ancestry controls.
The effect
The reported allele is C; the catalogue records no effect size
; p = 2 × 10−11.
Where it sits Chromosome 11, band 11q14.3 — between genes, 14.3 kb from MTNR1B.
What each result means
C/CTwo copies of the version the research linked to Gestational diabetes mellitus. That is the strongest link of the three results. A link in a study is not a diagnosis.
C/TOne copy of the version the research linked to Gestational diabetes mellitus. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Gestational diabetes mellitus. This is the starting point the study compared everyone against.

Questions about rs140662041
What is rs140662041?
rs140662041 is a single position in the genome, in or near the near MTNR1B gene. Published research associates it with gestational diabetes mellitus. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs140662041 linked to?
On MyGeneLog this position is linked to Gestational Diabetes Mellitus. The research behind each link, and its sources, are set out on that condition page.
Does having rs140662041 mean I will get this?
No. Common variants like this one move a probability slightly and, on their own, rarely decide anything about one person. Nothing on this page is a diagnosis, and health decisions should be made with a clinician who can see your whole picture.
Where does the information about rs140662041 come from?
GWAS Catalog, Frontiers in endocrinology 2026, PMID:42109742. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
